Hm, mine was only a couple years ago. I ordered a Swiftech H2O-220 kit, their Rampage Extreme NB block, different tubing and different fans. The installation went smooth and there was no leakage what-so-ever.

Just take your time and do not rush! Leaks don't really scare me anymore - as long as there is no power to the system and you let it dry out your okay. That is, if it gets passed the paper towel and shamwows I put down

Few years back on my LGA775 system. No leaks. Didn't even leak test or any of that stuff. Did end up with some leaks due to cheapy barbs (Primochill ones) after a couple months. Nothing serious though and nothing got killed.

My first setup was about 2 years ago, my first mistake i made was getting a thermaltake unit. That thing sucked ass lol. After that I did my first custom setup and my mistake there was cheap clamps with an mcp655 and a hose blew right off the cpu block and made an aweful mess. Board wasnt killed, but the lubricant in the coolant (primochill) didnt short anything out - it insulated everything from having juice go through it. Asus still RMAd the board lol.

Just put my custom waterloop together about a month ago after alot of research. Aparently I didn't research enough! Leaked in under 20 seconds. I Isolated the problem and the culrpit was the radiator. After a quick investigation, I found that I managed to pierce the radiator fins with the screws during mounting. Waterloop DELAYED until new radiator arrives.
